The demands for better emissions and fuel economy in the mid 1970s necessitated leaner fuel mixtures. These leaner mixtures required greater voltage and more spark to ignite. This challenge led GM ...

The ignition control module is a crucial component of a vehicle's ignition system. It is a control unit responsible for regulating the ignition timing and generating sparks to ignite the fuel-air ...

When General Motors introduced the High Energy Ignition (HEI) distributor in the mid-1970s, it was revolutionary. So much so that it still has a strong following among today's hot rodders. Like other ...

It seems like such a small thing—that tiny area approximately 0.040 of an inch wide inside each combustion chamber. That area we're talking about is the gap between the electrode and strap on each ...

Heat initiates the internal combustion process. Diesel engines utilize the temperature buildup from extremely high compression (pressure) to ignite the air/fuel mixture, with a little help from glow ...
